Issue #6242 has been reported by shugo (Shugo Maeda). ---------------------------------------- Feature #6242: Ruby should support lists https://bugs.ruby-lang.org/issues/6242 Author: shugo (Shugo Maeda) Status: Open Priority: Normal Assignee: Category: Joke Target version: 2.0.0 I've heard that Ruby is a LISP. LISP stands for "LISt Processing." Hence, Ruby should support lists. I've attached a patch to add the classes List and Cons, and the cons operator `:::'. Example: >> S[1,2,3].inject(:+) => 6 >> S[1,2,3] => S[1, 2, 3] >> 0 ::: S[1,2,3] => S[0, 1, 2, 3] >> 0 ::: 1 ::: 2 ::: 3 ::: nil => S[0, 1, 2, 3] >> S[1,2,3].inject(:+) => 6 -- http://bugs.ruby-lang.org/
